This study used 30 tape-recorded sentences taken from the Carrow Auditory Visual Abilities Test, then time-compressed by the Lexicon Varispeech II to 50%, in order to investigate age-related changes in auditory discrimination. Each sentence offers one or more phonemic contrasts (manner or place of articulation, voicing, frequency, or some combination). Overall group mean performance was not different between 6-yr-olds (N:14) vs 8-yr-olds (N:20), or between 10-yr-olds (N:16) vs 15 young adults, but the 2 older groups were each significantly better than each of the 2 younger groups. The ontogenetic progression of this auditory processing ability seems to mature in the early part of the second decade of life. Of 5 feature contrasts, only place of articulation was significantly more difficult, for all ages. Of 6 frequency contrasts, only that for high frequencies was significantly more difficult, for all groups, possibly due to an as yet undocumented damping of high frequencies by the time-compression apparatus.
本研究采用了从卡罗听觉视觉能力测试中选取的30个录音句子，然后通过Lexicon Varispeech II将其时间压缩至50%，以研究听觉辨别方面与年龄相关的变化。每个句子提供一个或多个音位对比（发音方式或部位、浊音、频率或某种组合）。6岁儿童组（N = 14）与8岁儿童组（N = 20）之间，或10岁儿童组（N = 16）与15名年轻成年人之间，总体组平均表现并无差异，但两个年龄较大的组均显著优于两个年龄较小的组。这种听觉处理能力的个体发育进程似乎在生命的第二个十年早期成熟。在5种特征对比中，对于所有年龄段而言，只有发音部位显著更难辨别。在6种频率对比中，对于所有组而言，只有高频对比显著更难辨别，这可能是由于时间压缩设备对高频进行了尚未记录在案的衰减。
